How to find out how many hertz on your Xiaomi phone

Modern Xiaomi and Redmi smartphones are equipped with displays with a high refresh rate, which makes the interface smooth and animations pleasant to the eye. However, it is not always obvious which hertzovka is installed by default, since the system often automatically adapts this parameter to the content. Users often wonder how to check the real value and make sure that their device is working at full power.

Understanding how to know how much hertz on a Xiaomi phone is essential not only to check the performance when buying, but also to optimize power consumption. Standard values range from 60 Hz to 120 Hz and above, but maximum mode activation can be hidden in the depths of the menu. In this article, we will break down all the diagnostic methods available, from built-in tools to third-party utilities.

It's worth noting that frame rates have a direct impact on autonomy, and the higher the value, the faster the battery is used, so it's important to be able to switch between modes, and we'll look at how to find this information without installing unnecessary applications and when to use professional tools.

Checking through standard MIUI and HyperOS settings

The easiest and safest way to find out the current hertz is to look at the system menu. The interface of the MIUI shell and the new HyperOS provides basic information about the display, although the detail often depends on the specific model of the smartphone. You need to go to the Settings section, then select the Screen or Display item.

Inside this menu, look for the refresh rate option, which is called the Refresh Rate or Refresh Rate on many Redmi and Xiaomi models, and if you choose the default or Auto, the system decides when to increase the hertz to 90 or 120 Hz and when to reduce it to save energy.

In some cases, especially on older firmware versions, a specific number (e.g. 90 or 120) may not be displayed explicitly but rather be represented by a Standard (60 Hz) and Preferred (maximum) switch. It is important to understand that selecting the Auto mode does not guarantee constant operation at maximum frequency, since Xiaomi algorithms aggressively reduce it in static menus.

💡

If there is no explicit choice of hertz on the menu, then your model supports only the standard 60 Hz or the system completely hides this option from the user.

For more accurate diagnosis, new versions of HyperOS have the ability to see the current frequency in real time, but this feature is not available on all devices. Most often, you will have to settle for presets without detailed monitoring in this section.

Using an engineering menu for accurate diagnosis

If the standard settings don't give you a complete answer, you can use the hidden engineering menu, which is a powerful hardware testing tool that allows you to see the technical parameters of the display. To get there, open the Phone app and type in the combination ##6484##.

Once you enter the code, the CIT (Customer Information Test) menu will open, and you will scroll through the list and find the item associated with the screen, usually called Version, Display or Touchpanel. Depending on the model, frequency information can be specified in the text description of the driver version or in a separate test.

Be careful when you move through the engineering menu. While it's safe to browse, changing the parameters in the test modes can cause the touchscreen to malfunction or calibrate colors. If you're not sure what you're doing, you'd better just read the data.

⚠️ Warning: Do not try to change the values in the engineering menu unless you know exactly what they are responsible for.This can lead to a software failure that requires reflashing the device.

On some Poco and Redmi Note models, you can run a Color or Touch test on this menu, where technical data, including current hertzing, is sometimes displayed in the corner of the screen, but this method does not work on all MIUI builds.

Third-party screen monitoring applications

When built-in tools are scarce, specialized applications from the Google Play Store come to the rescue, reading data directly from display drivers and showing accurate information in real time, and one of the most popular and reliable tools is the Device Info HW or AIDA64 app.

Once you install and run this software, you'll need to go to the Display or Screen section, and you'll see a detailed spec sheet that shows you the maximum frequency you're supporting and, in some cases, the current value, and that's the most reliable way to know the truth.

Another useful tool is Screen Test or Test Your Screen, which not only shows the hertz, but also allows you to perform a visual test by running animations that show the smoothness of the matrix. If the screen is really running at 120 Hz, the movement of objects will be noticeably smoother than 60 Hz.

Using third-party software requires permissions to access device information, and make sure you only download applications from trusted developers to ensure that data security is not compromised.

Visual inspection and smoothness tests

There's an easy way to test hertz without technical tools, a visual test. The human eye can tell the difference between 60 Hz and 90/120 Hz, especially when you scrolle through the news feed or scroll through the settings menu. If the interface floats and seems twitchy, the standard mode is likely activated.

For a more objective assessment, you can use online tests such as TestUFO or specialized sites to check FPS. Open your browser on your phone, run the test and observe moving objects. At high refresh rates, the movement will be clear, without plumes and blur.

Also worth paying attention to is the behavior of animations when opening apps: At 120 Hz, transitions take less time and look more natural, while at 60 Hz, there may be micro-latency or "stepping" of movement.

This is subjective and depends on the sensitivity of your vision, but it gives you a general idea of how the display works. If you go from a normal 60-hertz screen, the difference is enormous even without the instrument.

Comparison of refresh rates on different models

Xiaomi's different smartphone lines support different frequency standards. Budget models are often limited to 60 or 90Hz, while flagships offer 120Hz and above. Understanding these differences helps to set the device up properly.

The table below compares the typical values for different series of devices:

As you can see from the table, adaptive frequency (LTPO) is found mainly in expensive models, which allows the screen to reduce the hertz to 1 Hz when viewing a static picture, which significantly saves charge. In simpler models, the switching occurs discretely, for example, only between 60 and 90 Hz.

Owners of gaming smartphones in the Black Shark or Redmi K series should remember that the maximum frequency (for example, 144 Hz or 720 Hz touch sensor) is activated only in supported games.

The impact of hertzovka on autonomy and productivity

Increasing the refresh rate of the screen inevitably leads to increased power consumption. The processor and graphics accelerator are forced to render more frames per second, which puts additional strain on the system. If you are critical to autonomy, it makes sense to reduce the hertz.

However, modern Snapdragon and MediaTek processors have learned to cope with this load effectively, and in everyday tasks, the difference in battery consumption between 60 and 120 Hz may not be as noticeable as previously thought, especially on screens with LTPS or LTPO technology.

💡

Reducing the frequency to 60 Hz can increase the smartphone’s life by 10-15%, but will make the interface less responsive.

If you notice that the phone discharges quickly or warms up when you’re actively working with the interface, try forcefully setting 60Hz in the settings.This can also help with older games that aren’t optimized for high frequencies and can produce unstable FPS.

⚠️ Warning: Some heavy games may not support high hertz, regardless of screen settings.In such cases, the phone will run at 60Hz automatically to keep frames stable.

The balance between smoothness and energy is a personal choice for each user, with some people willing to charge their phones more often for the perfect picture, and others preferring to be reliable for two days.
